IIS 6.0 F1: Application Configuration - Cache Options Tab

Applies To: Windows Server 2008 R2

Use this tab to set your application caching options. You can configure Internet Information Services (IIS) to not cache any Active Server Pages (ASP) files on the client. This forces the client browser to query the server for a new (or updated) page at each request. Although this process saves disk space on the client computer, performance is reduced. Caching ASP script files enhances performance because cached ASP scripts are not compiled each time they are called.

Do not cache ASP files

Click to ensure that no ASP files are cached by the browser. As a result, every repeated request from the browser results in a fresh request of the ASP file from the server.

Cache all ASP files in memory

Click to ensure that all ASP files that have been requested by the browser from the server are cached on this computer. If you choose this option, you should identify a directory in the Disk cache directory box and set a limit for script engines cached in the Number of script engines cached box.

Cache limited ASP files in memory

Click to cache a limited number of compiled ASP files (templates) in memory. Type (or click the up and down arrows to set) the number of files you want to cache in the box. After you click this option, choose one of the following options to either cache all remaining ASP files or to cache a limited number of the remaining files on disk.

Cache remaining ASP files on disk

Click to cache all remaining compiled ASP files (those files not cached in memory) to disk.

Cache limited ASP files on disk

Click to cache a limited number of compiled ASP files (those files not cached in memory) to disk.

Disk cache directory

Type or browse to the target directory to house the ASP files.

Browse

Click to locate a directory on this computer to store cached ASP files.

Number of script engines cached

Type a number or click the up and down arrows to control the number of script engines cached. Script engines, such as Microsoft® Visual Basic® Scripting Edition (VBScript), require memory and accessibility. By limiting the number of script engines cached on your computer, you can better manage performance and memory.
